The sentence has a few grammatical issues and could be clearer. Here's a revised version:
"I love pretentious's videos, but MAN, I can’t stand it when he talks about MHA 💔💔 (when it’s not production-related)."
Key changes:
- Added a comma after "videos" to separate the two independent clauses.
- Added a comma after "MAN" for clarity.
- Changed "abt" to "about" for formality.
- Added a hyphen in "production-related" to indicate that it is a compound adjective.
